Critical dynamics and tree-like spatiotemporal patterns in exciton-polaritoncondensates
Nataliya Bobrovska, Andrzej Opala, Paweł Miętki +4
We study nonresonantly pumped exciton-polariton system in the vicinity of the dynamical instability threshold. We find that the system exhibits unique and rich dynamics, which lead…
Josephson vortices in a long Josephson junction formed by phase twist in a polariton superfluid
Davide Caputo, Nataliya Bobrovska, Dario Ballarini +7
Quantum fluids of light are an emerging platform for energy efficient signal processing, ultra-sensitive interferometry and quantum simulators at elevated temperatures. Here we dem…
Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
E. Estrecho, T. Gao, N. Bobrovska +12
Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor) provide a solid-state platform for studies of non-equilibrium quantum systems with a spon…
Dynamics of defect-induced dark solitons in an exciton-polariton condensate
Andrzej Opala, Maciej Pieczarka, Nataliya Bobrovska +1
We study theoretically the emission of dark solitons induced by a moving defect in a nonresonantly pumped exciton-polariton condensate. The number of created dark solitons per unit…
Spontaneous condensation of exciton polaritons in the single-shot regime
E. Estrecho, T. Gao, N. Bobrovska +9
Bose-Einstein condensate of exciton polaritons in a semiconductor microcavity is a macroscopically populated coherent quantum state subject to concurrent pumping and decay. Debates…
Doubly dressed bosons - exciton-polaritons in a strong terahertz field
B. Piętka, N. Bobrovska, D. Stephan +12
We demonstrate the existence of a novel quasiparticle: an exciton in a semiconductor doubly dressed with two photons of different wavelengths: near infrared cavity photon and terah…
Dynamical instability of a non-equilibrium exciton-polariton condensate
Nataliya Bobrovska, Michał Matuszewski, Konstantinos S. Daskalakis +2
By imaging single-shot realizations of an organic polariton quantum fluid, we observe the long-sought dynamical instability of non-equilibrium condensates. Without any free paramet…
Adiabatic approximation and fluctuations in exciton-polariton condensates
Nataliya Bobrovska, Michał Matuszewski
We study the relation between the models commonly used to describe the dynamics of nonresonantly pumped exciton-polariton condensates, namely the ones described by the complex Ginz…
Bright sink-type localized states in exciton-polariton condensates
Michał Kulczykowski, Nataliya Bobrovska, Michał Matuszewski
The family of one-dimensional localized solutions to dissipative nonlinear equations includes a variety of objects such as sources, sinks, shocks (kinks), and pulses. These states…
Stability and spatial coherence of nonresonantly pumped exciton-polariton condensates
Nataliya Bobrovska, Elena A. Ostrovskaya, Michal Matuszewski
We investigate the stability and coherence properties of one-dimensional exciton-polariton condensates under nonresonant pumping. We model the condensate dynamics using the open-di…
